To all whom. it may concern:

Be it known that 1 Hana; A. H1CKS, a citizen of the United States, residing at Gerty, in the county of Hughes and State of Oklahoma, have invented certain new and useful Improvements in Electr1c-lV1re-Supporting Devices; and I do declare the fol.- lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements 1n supporting devices for telephone and telegraph wires.

One object of the invention is to provide simple and eiiicient means for securely and reliably connecting telephone and telegraph wires to a cross arm or bracket designed to be mounted on a suitable support.

Another object of the invention is to provide an electric wire support equipped with a simple and eilicient insulator and with means for retaining said insulator in operative position on its supporting arm or bracket.

lVith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l represents a side elevation of a telephone pole equipped with a cross arm provided with this invention. Fig. 2 is a similar View partly in section of a pole equipped with a bracket provided with this invention. Fig. 3 is a transverse vertical section taken on the line 33 of Fig. 1. Fig. at is a horizontal section taken on the line 4-4 of Fig. 1. Fig. 5 is a longitudinal vertical section thereof.

In the embodiment illustrated in Fig. 1, a pole A is shown provided with a cross arm 1 having a plurality of longitudinally spaced notches 2, which are designed to receive the Wire supporting insulators as 3, any desired number of such notches being employed according to the number of wires to be supported, it being understood that one notch is necessary to support each wire. These cross arms may otherwise be of any suitable or desired construction and may be connected with the pole by suitable braces 4 or in any other suitable manner.

In Fig. 2 the pole A is shown equipped with a plurality of vertically spaced sup 'porting brackets 5 which extend laterally from said pole and are preferably connected therewith by screwing one end thereof into screw threaded sockets formed in the pole, as is shown clearly in Fig. 2, said brackets being provided with insulator receiving notches or recesses 6 similar to the notches 2 of the cross arm. The wire supports, which. are applied to either the cross arm or the bracket, are exactly the same, and hence one description only will be necessary. The notched supporting bracket or cross arm to which the insulating support is designed to be applied is provided at opposite sides of the notches therein with vertically disposed guides 7 into which the insulators 3 are adapted to be slipped and held thereby against lateral movement. These insulators 3 are composed of any suitable insulating material such as orporcelain, and are preferably inverted U-shape in cross sec tion, the legs 8 and 9 thereof being designed to straddle the arm or bracket to which they are applied, and the free ends of said legs extend below the lower edge of said bracket or arm to prevent any danger of the tie wires coming in contact with the supporting arm or bracket, which is preferably composed of metal. These insulators are each provided with a groove 10 which extends transversely therearound and is of suiiicient depth to completely house the tie wire and the line wire designed to be connected therewith, the line wire being arranged in the portion of the groove which extends transversely across the upper end or cross bar of the insulator, as shown clearly in the drawings. A clamping n'lembcr or cap ll is connected with the supporting bracket or arm, being preferably pivoted at one end thereto and being made of sufficient length to span all of the notches .or recesses formed in the bracket or arm to which it is to be applied. The free end of this clamping member is detachably connected with the arm or bracket in any suitable manner, being here shown provided with a spring catch 12 which engages the free end of the arm to which it isapplied and securely holds the cap in operative position over the upper ends of the insulators. These clamps are provided on their inner faces with insulating blocks 13 secured thereto at suitable points to dispose them over the insulators mounted in the notches or recesses of the arms or brackets .to which they are applied, said blocks serving to completely insulate the clamping member,which is preferably made of metal-from the line and tie wires supported by insulators 3. The guides 7 project at their upper ends above the upper end or cross barof the insulator when the latter is in operative position to. provide a suitabl seat for the insulator blocks 13 secured to the inner face of the clamping members.

In the use of this improved device, the cross arm or brace to which it is to be applied being provided with the necessary notch to form a seat for the insulator 3, said insulator is slipped vertically over the arm or bracket between the guide 7 and fits within the notch of the bracket or arm with the free ends of its legs projecting below the lower edge of said bracket. The line wire to be supported is then placed in the groove across the top or cross bar of said member 3, and a tie wire 14 is wrapped atone end around the line wire at one side of the insulator and is then carried down around the insulator 3 and up over the top thereof, crossing the line wire, and is brought up to the other side of the member 3 where it'is wrapped securely around the line Wire at that side of the insulator, the tie wire being disposed within the groove 10 which extends around the insulator, the side Walls of the' groo e projecting on each side beyond the tie wire sufliciently to prevent the current from jumping the tie wire and passing to other metal parts of the support. These projecting side walls cause the current, should it jump the tie wire, to pass out into the air and thus do no harm. The cap 11 is then placed in operative position over the insulator with the block 13 secured thereto disposed in the seat formed between the guides above the insulator. This block.

is also provided with a groove 15 which extends transversely thereof and is positioned to register with the groove in the top of the insulator 3, It will thus be obvious that line Wires mounted as above described Will be permanently held in operative position and repairs reduced to aminimum.

I claim as my invention:

1. A supi, 'rting device for electric wires comprising an arm having longitudinally spaced guides, a bifurcated insuiatormounted between said guides and straddling said arm, and means for securing said insulator in operative position.

nosaeeo 2. A supporting device for electric wires comprising an arm having a recess, and an insulator inverted U-shape in cross section straddling said arm and seated in said recess.

3. A supporting device for electric wires comprising an arm having longitudinally spaced guides, a bifurcated insulator slidable between said guides and straddling said arm with the free ends thereof extending beyond the arm, said insulator having a groove extending transversely therearound, and a clamping member arranged over said insulator.

4. A supporting device for electric wires comprising an arm having longitudinally spaced guides, a bifurcated insulator slidable between said guides and straddling said arm with the free ends thereof extending beyond the arm, said insulator having a. groove extending transvers' l f therearound, and a clamping member arr: igcd over said insulator and provided with an insulating block having a groove registering \V iLll the groove in the insulator.

5. In a supporting device for electric wires, the combination with an arm having a recess therein with guides at opposite ends of said recess, of a bifurcated insulating member slidable in said guides and adapted to seat in said recess, and an insulator securing member removably secured to said arm and having an insulating block arranged to fit over said insulator when in operative position.

6. Ina supporting device for elect wires, the combination with an arm hav a recess therein with gl'lltlt at opposite of said recess, of a bifunated insul member Sildfiblt! in said guides and ada "d to seat in s vid recess, and an insulator securing member removably secured to said arm and having an insulating biocl: ar ranged to fit er said insulator when in operative position, said block and insulator having registering wire receiving grooves therein. i

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
